Abstract

A Circular Hydraulic Jump is a phenomenon that is shaped when a vertical fluid jet impinges on a horizontal plate, at a certain radial distance of the plate center (Hydraulic Jump Radius). Most of the experimental and numerical studies have analyzed the Circular Hydraulic Jump on the flat target plate and the effect of the concave plate has not been investigated yet. Therefore, in this study, using the experimental investigation and numerical simulation using Fluent software, the effect of the Concave Target Plate on the size and shape of the hydraulic jump is investigated for the first time. In order to simulate the Circular Hydraulic Jump, the volume of fluid method (VOF) has been applied. The continuous surface force model (CSF) has been used to investigating the surface tension. The geometric reconstruction has been used for determining the interface of the two fluids. According to the experimental results, the Hydraulic Jump Radius is a function of the Impingement Jet Radius, the Concave Target Plate radius, and the volumetric flow rate. Also, based on the experimental observation, by increasing the radius of the Concave Target Plate, the shape of these jumps change from the circular to the polygonal hydraulic jump.
